\\^THIS DOCUMENT DESCRIBES THE ^^DEC\\SYSTEM-10 ^SYSTEM ^PERFORMANCE ^EVALUATION ^PACKAGE.
^THIS PACKAGE WAS DEVELOPED BY THE ^WESTERN ^MICHIGAN ^UNIVERSITY (^^WMU\\) ^ACADEMIC ^COMPUTER ^CENTER.
.B
^THE PERFORMANCE EVALUATION PACKAGE CONSISTS OF THREE PARTS:
.B;.LM8
^&^PART 1\&--^MONITOR CODE THAT ALLOWS YOU TO COLLECT PERFORMANCE DATA.
(^SEE ^SECTION 2.1.)
.B
^&^PART 2\&--^A USER-MODE PROGRAM THAT ALLOWS YOU TO RECORD THE DATA ON DISK.
(^SEE ^SECTION 2.2.)
.B
^&^PART 3\&--^A NUMBER OF USER-MODE PROGRAMS THAT ALLOW YOU TO PRODUCE REPORTS, SUMMARIES, AND A GRAPH.
(^SEE ^SECTION 2.3.)
.B2;.LM0
^THE OBJECTIVES OF THE PERFORMANCE EVALUATION PACKAGE ARE:
.LS;.LE;^TO PROVIDE INFORMATION ON THE USAGE OF IMPORTANT SYSTEM RESOURCES.
.LE;^TO PROVIDE A USEFUL TOOL FOR ANALYZING SYSTEM PERFORMANCE.
.ELS
.B
^WHEN YOU USE THE PERFORMANCE EVALUATION PACKAGE, YOU CAN
COLLECT AND RECORD DATA AT THE FOLLOWING LEVELS:
.B;.LM8
^&^LEVEL 1\&--CONTAINS THE DATA REQUIRED TO PRODUCE THE ^RESOURCE ^UTILIZATION ^GRAPH (^FIGURE ^A-1) AND THE ^RESOURCE ^UTILIZATION
^REPORT, ^^RPTA\\ (^FIGURE ^A-2).
.B
^&^LEVEL 2\&--CONTAINS ALL OF THE DATA IN LEVEL 1 PLUS THE
ADDITIONAL DATA REQUIRED TO PRODUCE THE REPORTS THAT ALLOW YOU
TO TUNE THE SCHEDULER (THAT IS, ^^PQ\\1 ^REQUEUE ^DATA, ^^RPTB\\
(^FIGURE ^A-3), ^PROCESSOR ^QUEUE ^DATA, ^^RPTC\\ (^FIGURE ^A-4),
^SPECIAL ^QUEUE ^DATA, ^^RPTD\\ (^FIGURE ^A-5), AND ^CLASS ^PERCENTAGES, ^^RPTE\\ (^FIGURE ^A-6)).
.B;.LM0
^YOU MAY PRINT THE ABOVE REPORTS INDIVIDUALLY OR IN GROUPS IF THE MONITOR
IS ASSEMBLED AT LEVEL 2.
.B
^IN ADDITION TO THE REPORTS LISTED ABOVE, YOU MAY PRODUCE A ^SUMMARY ^REPORT, ^^RPTS\\ (^FIGURE ^A-7), TO
SUMMARIZE THE DATA IN ^^RPTA, RPTB, RPTC\\, ^^RPTD\\, AND ^^RPTE\\ AT ANY INTERVAL.
.B
^CHAPTER 4 CONTAINS A COMPLETE DESCRIPTION OF EACH OF THESE REPORTS.
.NUMBER CHAPTER 2
.CH ^&^^MONITOR DATA COLLECTION CODE AND PROGRAM DESCRIPTIONS\\\&
\\^THIS CHAPTER DESCRIBES ^PARTS 1 THROUGH 3 OF THE PERFORMANCE EVALUATION PACKAGE.
.B
^SECTION 2.1, WHICH DESCRIBES THE MONITOR CODE THAT ALLOWS
YOU TO COLLECT PERFORMANCE DATA, CORRESPONDS TO ^PART 1.
^SECTION 2.2, WHICH DESCRIBES THE USER-MODE PROGRAM THAT ALLOWS YOU TO RECORD THE DATA ON DISK, CORRESPONDS
TO ^PART 2.
^SECTION 2.3, WHICH DESCRIBES A NUMBER OF USER-MODE PROGRAMS THAT ALLOW YOU TO PRODUCE A GRAPH,
REPORTS, AND SUMMARIES, CORRESPONDS TO ^PART 3.
.HL1 ^&^^PART 1--COLLECTING PERFORMANCE DATA\\(^MONITOR ^DATA ^COLLECTION ^CODE)\\\&
\\^THE STANDARD MONITOR TABLES CONTAIN THE DATA FOR LEVEL-1 RECORDING.
^THEREFORE, LEVEL-1 RECORDING DOES NOT REQUIRE ANY NEW CODE OR MONITOR TABLES.
^TO PERFORM LEVEL-1 COLLECTION, ASSEMBLE THE MONITOR BY SETTING THE
^^FTPSCD\\ ASSEMBLY SWITCH TO 0.
.B
^THE ^^SCDPER\\ MONITOR TABLE CONTAINS THE DATA FOR LEVEL-2 RECORDING.
^^GETTAB\\ 142 (^^GTSPA\\ UNDER FEATURE TEST SWITCH ^^FTPSCD\\) READS THIS DATA.
^TO PERFORM LEVEL-2 COLLECTION, ASSEMBLE THE MONITOR BY SETTING
THE ASSEMBLY SWITCH ^^FTPSCD\\ TO -1.
.HL1 ^&^^PART 2--RECORDING DATA ON DISK (LINES.MAC)\\\&
\\^THE ^^LINES\\ PROGRAM STARTS AS A DETACHED JOB RUNNING
IN [1,2] (OR ANY NUMBER WITH ^^SPY\\ PRIVILEGES).
^THEN, ONCE PER MINUTE, ^^LINES\\ RECORDS THE MONITOR PERFORMANCE DATA.
^EVERY 5 TO 10 MINUTES, ^^LINES\\ ADDS THE ACCUMULATED DATA TO THE END OF A DISK FILE.
^THE NAME OF THE DISK FILE IS IN THE FORM
.B;.TS25
	MMMDD.^^DAT\\
.B
WHERE
.B;.LM10;.TS10;.I-5
MMM	IS A 3-CHARACTER ALPHABETIC REPRESENTING THE MONTH
.B;.TS10;.I-5
#DD	IS A 2-CHARACTER NUMERIC REPRESENTING THE DAY OF THE MONTH
.B;.LM0
^FOR EXAMPLE, ON 9 ^MARCH THE FILENAME IS ^^MAR09.DAT\\.
.PG;.B
^YOU CAN CAUSE ^^LINES\\ TO ASSEMBLE IN SUCH A WAY THAT IT
CAN RECORD EITHER LEVEL-1 OR LEVEL-2 DATA ON THE DISK IF THE MONITOR
IS ASSEMBLED AT A SUFFICIENT RECORDING LEVEL.
^TO DO THIS, SET THE ^^FTSCHED\\ ASSEMBLY SWITCH TO THE FOLLOWING VALUES:
.LS;.LE;^TO RECORD LEVEL-1 DATA, SET ^^FTSCHED\\ TO 0.
.LE;^TO RECORD LEVEL-2 DATA, SET ^^FTSCHED\\ TO -1.
.ELS
.B
^^LINES\\ CHANGES ITS OWN PROGRAM NAME ONCE PER MINUTE TO DISPLAY THE
PERCENTAGE OF THE CENTRAL PROCESSOR (^^CPU\\) TIME USED IN THE LAST
MINUTE (THIS IS FOR READING FROM ^^SYSTAT\\, AND SO
FORTH).
.HL1 ^&^^PART 3--PRODUCING GRAPH, REPORTS, AND SUMMARIES\\\&
\\^SECTIONS 2.3.1 THROUGH 2.3.3 DESCRIBE THE USER-MODE
PROGRAMS THAT ALLOW YOU TO PRODUCE A GRAPH, REPORTS, AND DETAILED
SUMMARIES.
.HL 2 ^&^^SIMP1.FOR\\\&
\\^THE ^^SIMP1\\ PROGRAM IS THE PREPROCESSOR FOR THE ^^GRAPH1\\ PROGRAM.
^IT COMPRESSES ^^LINES\\ DATA INTO A NUMBER OF CONTIGUOUS
20-MINUTE INTERVALS WITH DATE HEADINGS.
.HL 2 ^&^^GRAPH1.FOR\\\&
\\^THE ^^GRAPH1\\ PROGRAM PRODUCES AN 8-1/2- BY 11-INCH GRAPH OF
24 HOURS OF DATA (7:00 AM TO 7:00 AM).
^THIS DATA CONSISTS OF THE FOLLOWING:
.LS;.LE;^THE AMOUNT OF ^^CPU\\ TIME USED.
.LE;^THE NUMBER OF LINES USED.
.LE;^THE RATE OF SWAPPING.
.LE;^THE RATE OF READING AND WRITING ON THE PUBLIC DISK STRUCTURE.
.ELS
^TO TAILOR THE SCALING OF THE ^RESOURCE ^UTILIZATION ^GRAPH TO YOUR INSTALLATION,
YOU MUST SUPPLY VARIOUS INSTALLATION-DEPENDENT PARAMETERS
AND THEN REASSEMBLE THE ^^GRAPH1\\ PROGRAM. ^^GRAPH\\1 CONTAINS THE
FOLLOWING TWO SETS OF PARAMETERS:
.B;.LM13;.TS13;.I-8
^&^SET 1\&#-#^THE PARAMETERS THAT DETERMINE THE MAXIMUM SCALE VALUES
USED IN PLOTTING.
.B;.I-8
^&^SET 2\&#-#^THE PARAMETERS THAT DETERMINE THE SCALE VALUES
USED IN PRINTING THE MAXIMUM PERCENTAGE FOR ANY 1-MINUTE INTERVAL.

^FOR AN EXAMPLE OF EACH OF THE REPORTS, SEE
^FIGURES ^A-1 THROUGH ^A-7 IN THE ^APPENDIX.
.HL1 ^&RESOURCE UTILIZATION GRAPH\&\\
\\^THERE ARE FOUR RESOURCES RECORDED ON THE ^RESOURCE ^UTILIZATION ^GRAPH (^FIGURE ^A-1).
^EACH OF THESE RESOURCES IS IDENTIFIED BY A UNIQUE LETTER CODE.
(^SEE ^TABLE 4-1.)

.B2;.LM0
^IN ADDITION, THE CODE LETTER ^O APPEARS WHEREVER TWO OR MORE RESOURCES OVERLAP.
.B
^THE VERTICAL SCALE ON THE GRAPH REPRESENTS THE PERCENTAGE OF
RESOURCES USED.
^FIGURE ^A-1 IS PLOTTED USING THE MAXIMUM VALUES INDICATED IN ^TABLE 4-1 AS 100 PERCENT.
^HOWEVER, YOU MAY SPECIFY OTHER VALUES AS PARAMETERS IN THE GRAPH PROGRAM TO CHANGE THE SCALE.
^IN OTHER WORDS, YOUR 100 PERCENT NEED NOT BE BASED ON THE SAME MAXIMUM VALUES AS THE 100 PERCENT IN ^FIGURE ^A-1.
.B
^THE MAXIMUM SWAPPING RATE OF 72,000 BLOCKS PER MINUTE IS BASED
SOLELY ON THE HARDWARE TRANSFER SPEED; IT DOES NOT TAKE INTO
CONSIDERATION EITHER HARDWARE- OR SOFTWARE-LATENCY TIMES.
^THEREFORE, YOU MAY NOT SPECIFY MORE THAN 72,000 BLOCKS PER MINUTE,
NO MATTER HOW MANY BLOCK SEQUENCES ARE TRANSFERRED.
.PG;.B
^ON THE OTHER HAND, THE DISK RATE OF 5,000 BLOCKS PER MINUTE IS BASED ON SINGLE-TRANSFER
128-WORD BLOCKS.
^THIS FIGURE IS ULTRACONSERVATIVE IF LARGER BLOCKS ARE WRITTEN
(AS OCCASIONALLY HAPPENS).
.B
^THE MAXIMUM OF 64 LINES IS BASED ON THE TOTAL NUMBER OF TERMINAL PORTS THAT ARE AVAILABLE TO USERS.
.B
^THE DATA IS PLOTTED FOR 20-MINUTE INTERVALS FROM DATA THAT IS
RECORDED AT 1-MINUTE INTERVALS.
^IN OTHER WORDS, THIS IS A SUMMARY OF A 20-MINUTE PLOT.
.B
^THE HORIZONTAL SCALE ON THE GRAPH REPRESENTS THE TIME OF DAY.
^IT BEGINS AT 7:00 AM OF THE INDICATED DAY  
AND ENDS AT 7:00 AM OF THE FOLLOWING DAY.
.B
^AT THE BOTTOM OF THE GRAPH SEVERAL MAXIMUM VALUES ARE PRINTED TO SHOW THE HIGHEST VALUES OF THE
INDICATED VARIABLE FOR ANY RECORDED 1-MINUTE INTERVAL DURING THE DAY.
^TYPICALLY, THESE VALUES ARE LARGER THAN ANY POINT PLOTTED ON THE GRAPH.
^THIS IS BECAUSE THE GRAPH PLOTS A SUMMARY (AVERAGE) OF A 20-MINUTE INTERVAL.
^WHERE APPLICABLE, THE USER-DEFINED MAXIMUM VALUE IS INDICATED
AFTER THE OBSERVED MAXIMUM PERCENTAGE. ^REMEMBER, IF YOU WISH, THESE
VALUES CAN BE DIFFERENT FROM THE SCALE VALUES USED IN ^FIGURE ^A-1.
.LM0
.HL1 ^&RESOURCE UTILIZATION REPORT (RPTA)\&\\
\\^^RPTA\\ CONTAINS THE MINUTE-BY-MINUTE DATA FROM WHICH THE
^RESOURCE ^UTILIZATION ^GRAPH IS PLOTTED, PLUS A NUMBER OF ADDITIONAL DATA ITEMS.
